That map is perfect except it says there is a barricade. There's not, you go right up to the stage. But it's a cool place to see shows (well, it was anyway).
I was there. The dude jumped an EIGHT FOOT (maybe 7 - still huge) fence. It was a huge fence. Not an easy task. A security guard did see him, and he chased him through the club. The thing you have to keep in mind:
1. He didn't know he had a gun until he got to the stage.
2. The dude was huge. The show was only 8 bucks. The dude thought it was just some random dude who didn't pay. Nobody wants to lose their teeth or go to the hospital over 8 bucks.
3. The dude ran and once he was at the stage it was too late.
I was there, and I know exactly how it happened. And I don't, not even for one second, blame the security. They did their job and some of them lost their lives trying to stop this. This madman was intent on killing, and that's exactly what he did.
Also, as for the patio, there were actually quite a few people outside. It was December but it was a pretty warm december overall. A dude with a food cart was out on the patio cooking for everyone and we were outside eating (I did twice). I stood in the back right by that patio door most of the night, during all of the local bands' sets, by the restroom chatting with friends. I feel shitty for this because early in the night, I had to ask to go outside the main club entrance to get some food because the patio door wasn't open. After a few people asked, they decided to open that door. Of course, they would have ended up opening it anyway. But these are the negative thoughts that go through your mind after something this awful
It started to get cold back there by the restrooms and pool tables about a half hour before it all happened and I remember giving some of the club's staff dirty looks and shivering thinking that the door should be closed. I wish I would have said something. It was propped open with a chair so people could keep going out to eat.
